In a sign of things to come for Coastal Tamil Nadu, Hindustan University at Padur recorded about 3 cms from early morning spell of rains. Similarly parts of North Chennai around Red Hills also recorded short spell of rains. There are isolated thunderstorms moving in from the sea which are likely to give sharp spells of rains in a few areas during the morning around Chennai.
Yesterday few places along the Western Ghats like Virudhunagar got moderate rains and things look good for today as well for places along the Western ghats to get some spells of rains in the interior areas due to wind convergence. During the course of the day thanks to the day time heating and the remnant moisture moving across the land mass from the East will trigger some “Veppa Salanam” Rains in the interior areas.
But the key thing which we need to keep in mind is the Low Level Winds are still more Northerlies rather than streamlined Easterlies. As we have mentioned many times in the past unlike the streamlined Easterlies the more drier Northerlies come in from the continent reducing the possibilities of heavy rains. South China Sea currently is hosting a tropical disturbance which has to complete its life cycle before Bay gets moisture intrusion from the South China Sea / NorthWest Pacific.
Late evening / night spells of rains likely in a few areas of Chennai, though these may be sharp spells it is unlikely to heavy for a long period. Sunny conditions might prevail during the day which might help the thunderstorms in the interior areas.
